I'd say that's pretty typical. The stocked trout seem to be 'relatively' easier to catch than wild salmon.
I don't know how many times I fished Ambleside last year, probably at least 20 times, only to catch one coho.
This spring I fished the Cap at least the same amount of times if not more, and only caught two fish, each within about 10 minutes of each other, when all the conditions were textbook ideal.
It takes a while to get a feel for how fast to retrieve to keep your gear off the bottom so it doesn't snag, how to set your float depth when drifting to keep it off the rocks.
I put so much money in the water at Ambleside the first year, it's not even funny. I hardly lose anything now.
Flyfishing is an entirely difficult category of frustration...
So, don't be discouraged, you just have to go through the process.
